Key Considerations When Evaluating Growth Marketing Agencies

As you analyze potential growth marketing agencies, there are several critical prospects to consider to make the most informed decision. These include:

Goals

Consider your business goals, such as lead generation, customer acquisition, retention, increasing revenue, or brand awareness. Are you looking for a larger market share, or are you seeking quicker growth within a specific industry? Knowing the answers will help determine which agency best suits you.

Experience

Evaluate each agency’s experience and track record by researching the services they have provided for other clients. Does the agency specialize in any specific industries? How long has the agency been in operation? What type of clients have they worked with, and what successes have they achieved?

Progress-tracking

Make sure that the agency can provide you with regular data reports and KPIs so that you can track the progress of your campaign. It’s important to know whether or not your efforts are paying off, and it will help guide future decisions.

In-house vs. outsourced

Depending on your needs, you may use an in-house growth marketing team, or an external agency. An in-house team provides more control and a better understanding of your business’s needs, while outsourcing can save time and money.

Specialization

Do you want a broad agency that can manage your entire funnel and that will give you guidance on where they should focus? Or do you prefer a more specialized agency that focuses on specific areas, such as SEO or PPC?

Terms

How long do you have to commit? Does the agency work on a retainer or on a project basis? What is the expected total cost, and are there additional fees such as setup or subscription charges?
